To all whom t may concern; 'It f Be it knOWn'thatIQJOHNW. BRANNAN',l acitizen of the vUnited States, residingzat Grand'lfsland, inthe'countyof Hall and State of Nebraska, have invented fcertain new anduse-ful 'Improvementsffin' Road Drag or Grading Machines7 of vvhiohpthefollowing is a specification, reference being had to theaccompanying'dravvings. f l* It is the purpose'of he present inventionto provide a machine of this character in-` volving mean'sfornotronlyloosening up the" ling the object tor fill the roller with fluid,

places and the ruts, but also for eliminatingthem, vgradingthe road androlling, 15

It will-be noted that the bar 32 and, its blade aredisposed on an in'cline transversely of the frame, so as lto deflect thedirt 'andthe like to one side of thermazchine, a's they vtravels overthe road bed.
